Telecommunication firms operating subsea fiber-optic cables currently rely on annual physical inspections by diving teams to detect outer armoring degradation. However, divers can only safely inspect shallow-water segments near coastal landings, leaving deep-sea stretches unexamined. To decrease catastrophic cable ruptures, a major operator plans to replace diving inspections with automated acoustic monitoring. This system emits continuous sonar pulses along the cable's internal core, detecting structural micro-fractures in the outer armoring across its entire length. The operator claims that implementing this technology will reduce the overall number of unexpected cable ruptures.
Which of the following, if true, provides the strongest support for the telecommunication operator's claim?
- APhysical diving inspections near coastal landings frequently identify biological encrustations that acoustic pulses cannot detect but which cause rapid corrosion if unaddressed.
- A significant majority of deep-sea cable ruptures originate from gradual micro-fracturing of the outer armoring rather than sudden events such as undersea landslides.Cevap
- CThe financial expenditure required to repair a severed subsea cable in deep water far exceeds the operating budget allocated for annual shallow-water diving inspections.
- DAutomated acoustic monitoring systems consume far less auxiliary power than the marine surface vessels deployed during physical diving operations.
- EIn controlled shallow-water trials, acoustic pulse monitoring identified outer armoring defects with higher consistency than diver inspections on short test cables.
